PIC32MX230F064BT-V/ML Visão geral
An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripherals onto one silicon die. The PIC32MX2xx family belongs to the wider PIC32MX family of 32-bit microcontrollers from Microchip, sitting between 8-bit PIC16/PIC18 microcontrollers and 32-bit Cortex-M devices in capability and complexity. Within this hierarchy, the PIC32MX230F064B series targets cost-sensitive 32-bit applications, providing a clear upgrade path from 8-bit designs.
Key features include two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible pin mapping, Parallel Master Port (PMP) for graphics interfaces, mTouch capacitive touch hardware support, and high-resolution 1 ns time measurement. An integrated on-chip temperature sensor adds system-level monitoring capability without external components. The 28-pin QFN package offers a compact 6x6 mm footprint suited to space-constrained designs.
The PIC32MX230F064B is built on a 32-bit MIPS M4K core with 5-stage pipeline, single-cycle multiplication, hardware multiply/divide, and an enhanced interrupt controller. PPS remaps digital peripherals to any I/O pin, simplifying PCB routing and BOM consolidation. The PMP engine supports 8-bit and 16-bit parallel data transfers for graphics or external memory interfaces.
Typical applications include automotive body electronics, industrial control nodes, capacitive touch user interfaces, low-cost graphics HMI panels, and sensor hubs. The automotive -V grade makes the part suitable for cabin and underhood ECUs where temperature extremes are expected. The 40 MHz performance and rich peripherals also fit HVAC controls, lighting controllers, and small appliances.
When designing, note the 64 KB Flash can be self-programmed under bootloader control. Use PPS to reassign UART/SPI/I2C pins without board rework. Add decoupling capacitors within 5 mm of every VDD/VSS pair, and keep the exposed pad soldered to a continuous ground pour for thermal dissipation.

Notas de projeto
Decouple VDD/VSS and AVDD/AVSS pairs with 100 nF ceramic capacitors placed within 5 mm of each supply pin. The PIC32MX230F064BT-V/ML datasheet section on hardware design guidelines recommends a 4.7 uF bulk capacitor at the regulator output to suppress core-current transients when the PLL engages. Keep analog and digital ground returns joined at a single point near the exposed pad to avoid ground bounce affecting ADC readings.
The 28-pin QFN (ML) package has an exposed thermal pad that MUST be soldered to a continuous ground copper pour for thermal dissipation. According to Microchip package thermal data, the theta-JA is approximately 30 C/W on a 4-layer JEDEC test board, allowing continuous 40 MHz operation across the full -40C to +125C range. Avoid using the QFN in air-cooled enclosures with poor airflow; consider the SPDIP -SP variant for prototype thermal validation.
Do not leave MCLR floating - the MCLR pin requires a 10 kohm pull-up to VDD or a dedicated reset supervisor. Floating MCLR is a common cause of erratic code execution on PIC32MX2xx designs. Also note that PPS assignments must be unlocked via CFGCON register before writing to the remap registers; an unlocked write is silently ignored and the GPIO remains on its default peripheral. Refer to section 12 of the PIC32MX230F064B family datasheet for the proper unlock sequence.
Place the 28-QFN (ML) on a 4-layer PCB with a solid ground plane on layer 2 directly under the package. Route high-speed signals (SPI, I2S, PWM) on the top layer with reference to ground, keeping traces short and impedance-controlled when length exceeds 25 mm. The 0.65 mm QFN pitch requires 0.2 mm trace/space manufacturing; choose 4 mil / 4 mil design rules to avoid fab rejects.
When using the Parallel Master Port (PMP) for graphics interfaces, add 22 ohm series damping resistors on PMD<15:0> lines to suppress overshoot on long board-to-board cables. The I2S modules can be clocked up to several MHz; AC-couple I2S data lines if connecting between separate ground domains. Always use the PPS feature to keep high-frequency peripheral pins clustered on one side of the package for short trace routing.
